The driving handle 10 is installed with a fixed mount 102 and a rotating bar 103 extending in the reverse direction at both ends of the connection section 101, and the rotating bar 103 has a plurality of first convex patterns to increase friction. (192), wherein the plurality of first convex patterns 192 are installed in the axial direction on the surface of the free end rather than the rotary bar 103; and the connector 14 is located in the first suction pipe perforation 141. At least one square convex pillar 142 is installed to extend on the side, the free end of the square convex pillar 142 has a gradually decreasing shape, and the surface of the square convex pillar 142 has the first suction pipe perforation ( approaches a plurality of first barb grooves 191 installed surrounding 141); The positioning ring (16) has a second suction pipe perforation (161), and the inner peripheral wall of the positioning ring (16) has a polygonal shape; And the cross-sectional bolt 18 extends a convex connector 182 on the side of the sealing surface 181, and the convex connector 182 has a plurality of second convex patterns 194 that increase friction, A plurality of second convex patterns are installed in the axial direction on the surface of the free end rather than the convex connector 182.

In the above description, furthermore, a plurality of second barb grooves 193 and a plurality of third barb grooves 195 are formed at one end of the free end other than the rotary bar 103 and the convex connector 182, respectively. It is being installed. In addition, the thickness of the first suction pipe perforation 141 is at least the thickness of the square convex pillar 142; The thickness of the second suction pipe perforation 161 is the thickness of the first suction pipe perforation 141.

Referring to FIGS. 3A to 3F, the connector 14, for example, has a plurality of square convex pillars 142 extending from the side of the first suction pipe perforation 141, and has quadrant symmetry, a right angle, and It shows a shape, a straight line, or other forms that radiate irregularly in all directions around the first suction pipe perforation 141.

Referring to Figures 4, 5 and 8, it is a schematic diagram of the driving handle 10 being coupled to the suction pipe 20, and after the rotation bar 103 of the driving handle 10 is enlarged, the rotation bar It can be seen that the plurality of first convex patterns 192 are convexly installed on the surface of 103 so that an uneven spacing arrangement appears on the surface, and the plurality of first convex patterns 192 are used to provide surface friction and axial terms. The pulling force can be increased, and when the driving handle 10 and the suction pipe 20 are combined, the suction pipe 20 and the rotating bar 103 are in contact with each other, and the plurality of first convex patterns ( 192) increases the friction between the suction pipe 20 and the rotating bar 103 to prevent the suction pipe 20 from easily falling off.

Referring to FIGS. 6, 7, and 9, the connector 14 is a schematic diagram of being coupled to the suction pipe 20, and the surface of the square convex pillar 142 is connected to the first suction pipe perforation 141.
